Answer:
As the temperature of the gas increases, the particles gain kinetic energy and their speed increases. This means that the particles hit off the sides more often and with greater force. Both of these factors cause the pressure of the gas to increase.
Explanation:
Answer:
NaNH₂₀
Explanation:
0.5 mol Na, 0.5 mol N, and 10 mol H
To obtain the empirical formulae, we find the mole ratio between the elements and this is done by dividing all through by the smallest mol (0.5)
Na = 0.5 / 0.5 = 1
N = 0.5 / 0.5 = 1
H = 10 / 0.5 = 20
The mole ratio is used to write the empirical formulae. It is given as;
NaNH₂₀
No elements visible!
Ions form between metals and non-metals.
Hope this helps!
Answer:
An apple,a person.a table,a computer,wood because they occupies space
non matter=Light, heat, kinetic and potential energy, and sound are non-matter because they are massless
